Uses of BlockLocation in org.apache.hadoop.fs
 

Subclasses of BlockLocation in org.apache.hadoop.fs
 class BlockStorageLocation
          Wrapper for BlockLocation that also adds VolumeId volume location information for each replica.
 

Methods in org.apache.hadoop.fs that return BlockLocation
 BlockLocation[] LocatedFileStatus.getBlockLocations()
          Get the file's block locations
 BlockLocation[] FilterFileSystem.getFileBlockLocations(FileStatus file, long start, long len)
           
 BlockLocation[] FileSystem.getFileBlockLocations(FileStatus file, long start, long len)
          Return an array containing hostnames, offset and size of portions of the given file.
 BlockLocation[] FileContext.getFileBlockLocations(Path f, long start, long len)
          Return blockLocation of the given file for the given offset and len.
abstract  BlockLocation[] AbstractFileSystem.getFileBlockLocations(Path f, long start, long len)
          The specification of this method matches that of FileContext.getFileBlockLocations(Path, long, long) except that Path f must be for this file system.
 BlockLocation[] FileSystem.getFileBlockLocations(Path p, long start, long len)
          Return an array containing hostnames, offset and size of portions of the given file.
 

Constructors in org.apache.hadoop.fs with parameters of type BlockLocation

LocatedFileStatus(FileStatus stat, BlockLocation[] locations)
          Constructor
LocatedFileStatus(long length, boolean isdir, int block_replication, long blocksize, long modification_time, long access_time, FsPermission permission, String owner, String group, Path symlink, Path path, BlockLocation[] locations)
          Constructor
 

Uses of BlockLocation in org.apache.hadoop.fs.viewfs
 

Methods in org.apache.hadoop.fs.viewfs that return BlockLocation
